Iran's oil ministry said Sunday that it would stop exporting oil to French and British companies. The announcement came just days after Iran threatened to cut supplies to some European Union countries in retaliation for sanctions put in place by the EU and United States.

The price of unleaded gasoline in the U.S. will likely hit a nationwide average of $4 by this summer, said Dan Dicker, oil trader and author of "Oil's Endless Bid." The last time prices topped $4 was 2008 and Dicker said there's a one in three chance that gas could reach $5 a gallon.

If gas prices do head to those lofty levels, that could put a crimp in the economic recovery as consumers will likely cut down on spending if they have to pay more to fill up their cars.

Just last month, higher gas prices were to blame for an uptick in inflation. And it's not just consumers who will suffer. Companies facing higher shipping costs may reel in their hiring plans, slowing job growth and putting a crimp into the overall economic recovery.

"This price juggernaut has taken on a life of its own since the Iran/Israeli threat flinging began and [the] boycott/sanctions war continues to ratchet upwards, and it's been made worse by the big run in stocks since the start of the year," said Dicker.

Capital Economics analyst Julian Jessop said the stock market rebound has contributed at least $5 worth of gains to the price of oil.

Israel has contributed to the market mayhem by openly considering an attack on Tehran's nuclear infrastructure.

Iran exports 2.2 million barrels of oil per day, a sliver of the 89 million barrels that is consumed worldwide on a daily basis. Less than one-fifth of Iran's exports are sent to Europe.

The move by Iran is "essentially an empty gesture, as the UK and France buy hardly any oil," said Jessop in a client note.
